Speed without guilt
Hitachi introduces its first small form factor drive spinning at 15,000 RPM that is ideal for high 
performance enterprise applications. This completes the portfolio of performance hard drives 
for enterprise-class applications in the mission critical storage tier. Compared to similar 3.5” 
drives from Hitachi, sequential performance is 29% higher and 11% higher as compared to its 
10K RPM sibling. The 64MB cache buffer is the largest in the industry in its class. In addition, 
Advanced Power Management technology is included to optimize power consumption 
which lowers datacenter energy usage and cooling costs. This drive uses 50% less power 
than similar 3.5” drives in the Hitachi lineup. The Ultrastar™ C15K147 drive is designed on 
the same platform as its 10K RPM sibling to reduce qualification time.
Use less space
The C15K147 consumes 70% less space compared to standard 3.5-inch enterprise class 
drives for storage efficiency. Yet, this drive delivers the performance and reliability required  
in high performance computing and mission-critical environments running 24x7 operations.  
The 6Gb/sec SAS interface moves data quickly and reliably with improved availability  
and scalability.
Compromise nothing
The Ultrastar C15K147 self-encrypting models conform to the Trusted Computing Group’s  
Enterprise A Security Subsystem Class encryption specification. Now, customers can reduce the 
costs associated with drive retirement and extend drive life by enabling repurposing of drives.
